Dose anybody know if anyone makes any tru-stone in pieces big enough to make a pot call out of? I'm thinking that this would be a pretty neat project, but after doing a google search I was only able to find tru-stone in either pen blanks or bottle stopper blanks. I understand that it would be pretty expensive if I could get some in the size that I would need, and that this stuff is pretty heavy, so the call would need to be thinner on the bottom & sides, but it is a project that I would love to tackle. I would rather not buy pen or stopper blanks & glue them together, looking for one solid piece 4" square (or something close) by 1-1/8" or so. Any help would be greatly appreciated.
